Question

This is my script, but it only prints spaces in the console. Can someone explain how I can get the attribute values from a XML file using xPath?

    XPathNavigator nav;
    XPathDocument docNav;
    XPathNodeIterator NodeIter;
    XmlNamespaceManager ns;

    Int32 elementCount;

    String windowName;

    private void Form1_Load(object sender, EventArgs e)
    {
        docNav = new XPathDocument("C:/BlueEyeMacro/DaMaGeX/Applications/WindowBuilder/GUI.xml");
        nav = docNav.CreateNavigator();
        ns = new XmlNamespaceManager(nav.NameTable); 
        elementCount = nav.Select("/GUI/window").Count;
        Console.WriteLine(elementCount);
        for (int i = 1; i <= elementCount; i++)
        {
            NodeIter = nav.Select("/GUI/window[@ID="+i+"]");
            windowName = NodeIter.Current.GetAttribute("name", ns.DefaultNamespace);
            Console.WriteLine("{0}", windowName);
        }
    }
}

XML File
<GUI>
<window ID="1" name="mainWindow" parent="0" type="0" text="My first window" options="Option 1;" actions="action 1;" exit="exit;" />
<window ID="2" name="secondWindow" parent="0" type="0" text="My second window" options="Option 1;" actions="action 1;" exit="exit;" />
<window ID="3" name="thirdWindow" parent="0" type="0" text="My third window" options="Option 1;" actions="action 1;" exit="exit;" />
</GUI>

I guess, you have to call NodeIter.MoveNext() first like in this code:

XPathNodeIterator nodesText = nodesNavigator.SelectDescendants(XPathNodeType.Text, false);

while (nodesText.MoveNext())
{
    Console.Write(nodesText.Current.Name);
    Console.WriteLine(nodesText.Current.Value);
}
